 |
|
Hi!
I've searched the help but still don't understand. I think I don't need to
know all the details either. But of course it's important that I know when I
should write __fastcall or _fastcall in front of a function
declaration/implementation and when I shouldn't.
If I don't know what it stands for (don't think I'll ever understand), had I
better leave it out everywhere? (Except for IDE-managed functions which
always seem to contain __fastcall)

Have a look at this page - I think you'll find it helpful:

Interesting results in the benchmark. I was thinking that such a small
loop would be cached totally into the CPU and run at CPU speed. Maybe if
he did the test with volatile keyword, on integers, then he may have
seen a difference?? :)

In my DOS programs I actually have to turn register assignment off in order
to do real time speech and Reaction Time collection.
